“…The combination of increasing mean sea level rise twice that of the global rate, coastal erosion and extreme weather events leave only defensive responses other than the option to retreat. Due to the high cost associated with building a seawall around the island, the first response was to use sand bags [27]. As the situation worsened, the community built a handcrafted seawall that was substituted in 2017 by a Government built seawall [28].…”

Extreme weather events and failure to adapt to the likely impacts of climate change are two of the most significant threats to humanity. Therefore, many local communities are preparing adaptation plans. Even so, much of what was done has not been published in the peer-reviewed literature. This means that consideration of adaptation options for local communities is limited. With the objective of assisting in the development of adaptation plans, we present 80 adaptation options suitable for coastal communities that can be applied by local governments. They are a catena of options from defend to co-exist and finally, retreat that progresses as impacts become less manageable. Options are organized according to their capacity to protect local properties and infrastructure, natural systems, food production, availability of fresh and drinking water and well-being of the local population, as these are likely to be affected by climate change. To respond to multiple threats, ‘soft’ options, such as awareness raising, planning, political articulation and financial incentives, insurance and professional skills enhancement, can be encouraged immediately at relatively low cost and are reversible. For specific threats, options emphasize change in management practices as pre-emptive measures. Key audiences for this work are communities and local governments starting to consider priority actions to respond to climate change impacts.

“…Third, and leading on from this, the tiered approach to risk assessment aligns well with emerging adaptive planning approaches to adaptation, commonly known as adaptation pathways (Haasnoot et al 2013;Walker et al 2013). Adaptation pathways overcome many of the uncertainties associated with climate change impacts, especially timing and rate of change, by defining threshold events as trigger points for decision-making and action (Bosomworth et al 2017;Lin et al 2017). In fact, there are few examples of adaptation pathways being used within adaptation planning to develop a staged approach to actions-more commonly, they have been used as a vehicle to enable community engagement and consultation (Barnett et al 2014).…”

A three-tier risk assessment process for climate change adaptation at a local scale

2019

Formal structures for evaluating climate change risk are important components of adaptation decision-making. In this paper, we present an accessible, cost-effective and user-tested climate change risk assessment framework which allows organisations to systematically apply a risk management process aligned with international standards to identify and manage their climate change risks. It is delivered through 'CoastAdapt', a resource supporting climate change adaptation in Australia. This three-tier framework offers four benefits to the adaptation process. First, it allows organisations to identify climate change risks and integrate them with their mainstream risk management process. Second, it makes optimal use of an organisation's limited adaptation resources by taking a tiered approach, so allowing an organisation to start from a low knowledge base using minimal resources and, only if required, then move to more complex and resource-intensive risk assessment processes. Third, it introduces a time-dependent vulnerability rating which recognises the particular characteristics of climate change risks-that they are long term and associated with a considerable degree of uncertainty. Finally, it takes into account business inter-dependencies that can exacerbate impacts but be overlooked in a sector-based impacts evaluation. In this paper, we highlight the appropriate context in which to use each risk assessment tier, explore key technical differences among the three tiers, describe performance testing and present one case study of application. We discuss the benefits of this tiered risk assessment approach in the context of broader adaptation planning.

“…Partly in the continuing search for methods that address these deep uncertainties, the approach of Badaptation pathways^has attracted interest in recent years-a search of Web of Science using the terms Bclimate change^AND Badaptation pathways^showed a steady growth from two articles in 2010 to 32 in 2017. By defining threshold events as trigger points for decision-making and action, adaptation pathways remove some of the uncertainty around the timing and magnitude of climate change (Haasnoot et al 2013;Ranger et al 2013;Bosomworth et al 2017;Lin et al 2017). There have been few practical attempts to apply adaptation pathways approaches within a formal risk management framework; examples that do exist include for the Thames Barrier in the UK (Ranger et al 2013), from the Philippines (Gilroy and Jeuken 2018), and from the Netherlands (Haasnoot et al 2013).…”
